Subject [jira] Created: (COLLECTIONS-218) CollectionUtils.select() does not return passed in collection
Date Tue, 18 Jul 2006 23:18:13 GMT
CollectionUtils.select() does not return passed in collection
-------------------------------------------------------------

                 Key: COLLECTIONS-218
                 URL: http://issues.apache.org/jira/browse/COLLECTIONS-218
             Project: Commons Collections
          Issue Type: Improvement
          Components: Collection
    Affects Versions: 3.2, 3.1, 3.0, 2.1.1, 2.1, 2.0, 1.0, 3.3, Nightly Builds
            Reporter: Stephen Kestle


collect has the following methods: 

Collection collect(Collection inputCollection, final Transformer transformer)
Collection collect(Collection inputCollection, final Transformer transformer, final Collection
outputCollection)

The first creates an ArrayList(), where the second takes an outputCollection and, for convenience,
returns it.

Select (and selectReject) currently the following methods:

Collection select(Collection inputCollection, Predicate predicate)
void select(Collection inputCollection, Predicate predicate, Collection outputCollection)

I propose changing the bottom method to return the passed in outputCollection.  It would simplify
calling code.
